How do you lift up the middle class in a developing country?

That was the challenge facing Peruvian entrepreneur Carlos Rodriguez-Pastor, who hired IDEO to build an entire network of schools powered by a progressive new learning model. IDEO’s mandate: to redesign Innova’s entire K–12 learning experience, from the curriculum to the teacher training to the school buildings, with an eye toward expansion and a goal to provide international-quality education at an affordable price—about $100 a month.

Innova Schools is a part of Intercorp, a family of 35 businesses that span everything from banks to retail stores and added schools to its portfolio. In 2010, the company had five existing schools but realized that its existing model could not grow. The shortage of well-trained, high-quality teachers in Peru, combined with rising land costs, meant the schools would need to radically change course to succeed.

To learn about scalable school models around the world, IDEO researchers visited inspirational schools and learning programs, and looked to analogous systems like retail, hospitality, and health care to understand their approaches to scale. Throughout the project, they collaborated with teachers, students, and the Innova Schools team in co-designing the work itself.

Together, Innova Schools and IDEO developed the curriculum, teaching strategies, buildings, operational plans, and underlying financial model to run the network of schools.

"I was blown away by Innova Schools," said Salman Khan, founder of Khan Academy. "It's inspiring to see such an affordable school deliver a quality of education that would rival schools in the richest countries."

The new Innova Schools combine teacher-led, project-based learning in small groups with self-directed time using digital learning tools. Teachers monitor students’ work online and offer personalized guidance. Parents can view their children’s progress online as well.

Dynamic learning environments include community spaces, media labs, rooftop study areas, amphitheaters, and cafés that are optimized for flexibility: furniture on wheels, movable walls, and efficient uses of space to allow for different modes of learning.

An online Teacher Resource Center includes a database of more than 18,000 custom lesson plans based on a progressive new teaching approach. The center helps teachers learn their craft and gives them a chance to connect across the network.

The business model of Innova Schools was developed at the same time as the school experience. Designers leveraged the economies of scale that come from building a network of schools and centralized tools, such as data systems that allow all the schools to learn together.

The project has allowed Innova to open more schools at an affordable cost to families, ultimately giving more of Peru’s youth the chance to compete in the global economy. This comprehensive approach to system design ranks as one of Latin America’s most ambitious privately funded educational projects, and is on track to become the largest private school network in the region. To date, Innova has opened 63 schools in Peru that are serving more than 50,000 students.

A good system design doesn’t end with strategy. The work on Innova Schools also had a huge influence on the company, according to Rodriguez-Pastor. Through the creation of new roles and an aligned set of values, Innova’s central office has become a much more nimble and creative organization. They’re constantly scanning the world for inspiration in how to best educate their students, while building out the new innovations. They realize that design thinking can become an integrated part of their daily management of this growing network of schools.

Western Digital, the leading provider of external digital-storage solutions and a pioneer in the field, and IDEO collaborated on a number of products that produced reliable, secure, high-performance hard drives for personal and professional use and have won numerous design awards.

The projects include:

• MyBook external hard drive: IDEO and Western collaborated to find a new design language for their external hard drive MyBook. In just six months, MyBook became the number-one hard drive in the Americas, and grew US market share by more than 50 percent.
• MyBook II: Looking to regain MyBook’s original number-one position in the hard drive market, IDEO and Western came together again to refresh the original design, finding ways to further differentiate the product and the brand, and winning a 2008 Spark Bronze Award.
• MyPassport: Western and IDEO designed the 320GB, ultra-portable USB-powered hard drive that appeals to the mobile user, which won both the 2008 IDEA Bronze Award from IDSA and BusinessWeek, and the 2009 iF Award.
• MyBook and MyPassport 3.0: Again, IDEO and Western collaborated on bringing the popular MyBook external hard drive to the next level in the hardware, the software, and the packaging. IDEO also created in-store merchandising, the graphics and information featured on product packaging (and the “out-of-box experience”).

The city of San Francisco wanted to help its people become better prepared in case of emergency. While no one feels totally prepared for a natural disaster, people who are most connected within a local network fare better in an emergency.

So the San Francisco Department of Emergency Management (SF DEM) and IDEO teamed up to create SF72, a revolutionary platform that helps to reach people where they are. In times of emergency, the city will need citizens to be self-supporting for 72 hours (or longer) before local services or outside help kicks in. With that in mind, IDEO developed an accessible platform to help people prepare for those 72 hours in simple ways that fit into their daily lives.

The SF72 website helps people with five important tasks: Get connected, gather supplies, watch stories, make a plan, and have access to an updated Google map. SF72’s content is hyperlocal, but IDEO and SF DEM also created an open-source toolkit for cities worldwide. From San Jose to Denver, other locales are using the simple toolkit to create a City72 platform of their own. Most recently, the city of Oakland collaborated with Code for America to develop its own platform. The City72 Toolkit enables SF72’s ethos of social connection for resilience to scale and grow—city by city.

Team Rubicon, formed in 2010 as a response to the devastating earthquake in Haiti, is made up of former military veterans who swoop into help in times of disaster. The organization started with six vets in the US who were eager to transfer their battlefield readiness in to frontline relief efforts, and has grown to more than 28,000 volunteers across the world.

To explore its growing global effort and to shape the future of the organization’s venture, Team Rubicon approached IDEO for help. After an 11-week collaboration with government, military, and veteran groups, a vision for Team Rubicon Global emerged. Inspired by sources as diverse as TED and The Hell’s Angels, the three-tier model consisted of an anchor network to share best practices across the organization and two supporting platforms designed to help countries with varying capacity and needs.

Team Rubicon Global coordinated its first deployment in April 2015, when a quake struck Nepal, sending US and UK teams to double down on the rescue effort. According to Vince Moffit, Team Rubicon USA Incident Commander, that incident alone validated the network effect of IDEO’s work. “We couldn’t have done this without Team Rubicon UK,” he said.

And for the veterans who are part of Team Rubicon, the shared desire to serve—applying skills ideally suited for disaster response—creates a renewed sense of purpose, community, and leadership that helps reintegration to civilian life.

Since we moved in, Andy Deakin and I have teamed up to build out our displays. As industrial designers, we’re not trained in the art of window displays, but we’ve developed our own principles, drawing on our work creating physical exhibits or immersive experiences—and the rules set by the Port Authority.

Unlike traditional window fronts, ours comes with an elaborate set of constraints. The building is owned by the Port Authority of San Francisco, which has strict guidelines for what can be put on display. No direct advertising, no big logos, and nothing that looks too much like retail. The location also presents its own challenges: We have to create something strong enough to compete with the towering Bay Bridge above, and the bright sunlight along the Embarcadero. And every design has to do double duty—it needs to have meaning for people walking by on the street, as well as our coworkers and clients inside the building.

Our latest window design centers on a new line of cycling bags IDEO created with Brooks England. This time, the biggest challenge was showing off the gear without making the window feel too much like a store. We pulled inspiration from displays and exhibitions we admired, then brainstormed and sketched different iterations as a team before landing on the final concept: a bright yellow bike strapped with a mountain of boxes, which act as shelves for the bags to perch on.

Here are our seven rules for window design.

1. Set the Focus

What is the central focal point of the visual story you’re telling? Distinguish between primary elements and stage-setters. Try using only one material throughout, or in the case of the Brooks window, dip everything in one color to simplify the backdrop and create a neutral stage for the centerpiece—the bags.

2. Exaggerate Scale

Playing with scale helps create a big impact—especially if you want to amplify small objects to fill an entire window. We loved the Selfridges window display of giant flowers for the Apple watch, and employed this trick when we built a display for the launch the launch of Tom and David Kelley’s Creative Confidence. For that project, we created a six-foot-tall stack of books to fill the window.

3. Repeat a Theme

Whether it’s boxes, sticks, chairs, or lightbulbs, selecting one item and repeating it to completely fill the space is a simple trick to create an impressive sense of complexity. Aesop is a master of this and we’ve borrowed the technique for numerous exhibits.

4. Create Depth

Many windows create the illusion of depth when they’re actually quite two-dimensional. Using layers and forced perspective—similar to the tricks of theatrical set design—helps to draw the viewer in. Thomas Brisebras’ MAKE installation was a great example. Seemingly random floating sticks transformed into the word MAKE as you walked past the window. His was certainly the most Instagrammed window we’ve created so far.

5. Add Momentum

When they're composed in a particular way, static compositions can feel almost like they are in motion. Objects can be suspended in midair or positioned to make it seem like they're flying through the scene. When we created our 2020 event window, we installed multiple Steelcase Node chairs to give the impression they were jumping in the air.

6. Design for Duration

Our window budget often limits the types of materials and construction methods we can use. But keeping the duration of the display in mind can help guide the choice of materials. If it is only intended to last for a few weeks, exploring what you can do with cardstock might make the most sense. Unionmade, a San Francisco store, does a nice job of repurposing everyday objects and designing with lo-fi materials to suit their quick refresh rate.

7. Above All, Entertain

And don’t forget inject some play and humor into the mix. Watching people on the street look up and get the joke is half the fun.

‍

When the IDEO San Francisco studio moved its office to Pier 28, we landed a whole new design challenge: a massive, floor-to-ceiling front window along the Embarcadero. For the first time, we had a public display case to highlight our events and projects, and we had to figure out how to best activate it, while sticking to some pretty strict rules.

Last year, about a month before the con, I came across a Bender Badge project by AND!XOR—a group of hackers from California—on Hackaday. The Bender Badge is a nod to the robot character from Futurama and it comes packaged with games and flashy lights in the shape of his head. It’s also designed to be hacked (the barrier to entry is low—it can be programmed using the Arduino IDE). It seemed like a good place to focus my excitement.

For years, I have been looking for an opportunity to design something for DEF CON that interacts with sound. Networking and parties are a big part of the con, and often these events feature live DJs and music. I also wanted to create a design that relates to Bender's personality—he's often drinking and smoking, so a cigar seemed appropriate. Optimal choice: a cigar-shaped microphone.

The Bender Badge comes equipped with a standard set of hardware components (buttons, LEDs, and a display). Since the project was still in development, and I didn’t know which parts would be in the final version, I decided to build an add-on. The badge kit features an STM32F103 microcontroller, which includes an analog-to-digital converter (ADC). This allows the microcontroller to receive analog audio data by sampling it at high speeds and converting it into digital values. My goal was to use a microphone to capture the surrounding audio data and then convert that data into frequency components via Fourier analysis—specifically, using the discrete Fourier transform (DFT). The results of the Fourier analysis can be displayed as a bar graph. This is commonly referred to as a spectral analysis, and in this case, it would focus on frequencies between 20 and 20,000 Hz (the range for human hearing).

Proof of Concept

I built the microphone circuit to make sure it was configured properly before creating the printed circuit board (PCB). The circuit starts with the microphone to capture surrounding audio. Next, the signal from the microphone is amplified so that the microcontroller can receive a wider range of data from the ADC, which results in better definition from the Fourier transform. Lastly, the amplified signal goes through a low-pass filter to suppress any frequencies above 20,000 Hz that could interfere with the analysis.

The greatest challenge during this stage was implementing the DFT on the STM32 microcontroller. Thankfully, there is an algorithm called the fast Fourier transform (FFT) that speeds up the computation for the DFT, but it's still a complex and time consuming calculation. Performing the FFT and then updating the display is a time-sensitive task. If the display is updated too slowly, it will look choppy and less responsive. Luckily, I came across a library developed by STMicroelectronics that was already optimized to work with my specific microcontroller.

Circuit Board Design

One of my biggest hurdles in designing the PCB was board size. I didn’t know the exact size of the Bender Badge, but I attempted to scale everything based on the buttons and the screen. From there, I figured out what size I wanted the circuit board to be so that it looked proportional to the badge. I was able to make the badge look like a cigar by adding silkscreen to the top layer (the label, paper edges, and ash at the end), and by cutting the PCB into a cigar shape.

I placed most of the surface mount parts on the bottom of the circuit board to keep them hidden. The microphone stayed on the top layer to efficiently capture surrounding audio. (It also fit nicely as part of the cigar label.) I also added orange LED "ash" to the end of the top layer to make it look like the cigar was lit. These LEDs were meant to be triggered by acoustic activity, so that they would flicker and look more like embers than a solid light.

Firmware Finalizing

Two weeks before DEF CON was set to start, I submitted the PCB design for fabrication, and I created a prototype of the board. The majority of the leftover work involved converting the FFT output into something that could be shown on the display. The FFT outputs an array of frequency groupings, known as bins, where the size of a bin (or frequency grouping) is based on the audio sampling rate and size of the FFT. The bin size can be thought of as the output resolution of the FFT, and for the cigar mic the bins are about 39 Hz (40,000 Hz/1024) wide. Bins are important because they contain information on the amplitude of frequencies within each group. If the cigar mic does not pick up any surrounding audio between 1-39 Hz (the first bin), the value for that bin will be close to zero; but if there is activity within that frequency range, there will be a value greater than zero relative to how loud that frequency source is.

The FFT bins are grouped to create a bar graph that displays frequency data logarithmically (fewer bins grouped together at lower frequencies, and more bins grouped together at higher frequencies) in an effort to resemble human hearing. The display consists of 32 individual bars that are 4 pixels wide.

Assembly and Debugging

Once the circuit boards came back from fabrication, the first step was to assemble and test one. I connected the output of the PCB (the connection that sends the captured audio data to the microcontroller’s ADC) to an oscilloscope to see if the microphone was capturing audio and if the preamplifier was increasing the amplitude. I encountered two errors in my design. First, the microphone was incorrectly oriented, and second, I had flipped two pins on the preamplifier, which resulted in significant distortion. Both were easy fixes, but added extra time to the assembly process. As a result, I was working up until I got to DEF CON, and then some.

Shortly after I arrived in Vegas, I met up with the AND!XOR guys and showed them my addition. They loved it, and within a few hours, I had my cigar wired up, and my code running on their Bender Badge. It was awesome (and relieving) to see it all come together. Now I just have to figure out what to do for DEF CON 25.

If you want to learn more, check out my GitHub page for the project, which includes PCB files and badge firmware.

Every year, it's hard for me to contain my excitement as DEF CON approaches, so I try to focus that enthusiasm into various projects. (For the uninitiated, DEF CON is one of the world’s largest hacking conventions. The days are long, the sleeping is limited, and it’s Vegas in the middle of summer.) In the past five-plus years, designing and programming custom badges to share at DEF CON has become increasingly popular.

Strolling down the Porto’s Rio Douro in the bright, spring sun, a Thoughtless Act caught my eye. A man selling knock-off sunglasses had thoughtfully—or instinctively—used the bench he'd been sitting on to display his wares.

It was the perfect display stand: the slats provided a neat grid format to lodge the glasses into so they could be fully admired from all angles, while the greyed wood gave a neutral backdrop to assess the color and design.

From a design research perspective, observing the way people exploit the objects and environments around them can provide fruitful and culturally-relevant inspiration. Taking ownership of public space and repurposing it for a transient commercial opportunity was natural to this street seller. We see other examples of nomadic, 'pop-up commerce' with things like food trucks and busking musicians.

It wasn't quite enough to persuade me to part with my euros, but it was a lovely example of Thoughtless Acts in action, nonetheless!

Human-centered design requires us to observe human behavior with beginner's eyes, so that we can spot the innate ways people interact with the world around them. We call these intuitive and unconscious reactions thoughtless acts, and IDEO designers collect photos of them to inspire the invention of new products, services, and experiences.

My husband always writes me a little bit of Valentine's Day Code. The image above is one of my favorites—Charlie was learning 3JS, a 3D web development framework, and made me my dream: an exploding pink disco ball floating in space. He's made a 3D simulation of Big Sur (where we took our first road trip together), a "Charlie Bot" (forking off of hubot, creating a fake Charlie for me to talk to when I was traveling a lot) and an Adventure-style text based game, where I got to achieve my dream of meeting Prince with my dog Hudson.

As a Biodesigner + Cardiologist at IDEO Palo Alto, I led three classes of 5th graders at Covington Elementary School (Los Altos, CA) in their annual sheep heart dissection this Valentine's Day. I introduced them to the fundamentals of cardiovascular anatomy and physiology, including the structure and function of each chamber and valve, their relationships to surrounding conduits, and the hemodynamics and electrophysiology that drive the system. You know, just the basics. All of the kids experienced a hands-on exploration of the heart’s surface and texture, then under the supervision of volunteering parents, dissected their ways into the depths of the organ. Accompanying me was my rockstar hostess and sidekick Celia Wedner, future doc and daughter of Palo Alto’s Grant Wedner.

I’ve been doing cross-stitch for more than 10 years. Cross-stitch is an ancient form of embroidery that’s very intricate—it takes a long time to finish a product! The time I spend making a pattern is one of my favorite ways of expressing love on Valentine's Day.

For our third annual Galentine’s Day gathering, we started by designing postcards to send to our district representatives. This was followed by whiskey tastings and a fancy dinner hosted in a room decorated with posters of inspiring power-women. Everyone left with a "treat yo-self" care package, complete with home decor, "Make Your Mark" to-do lists, homemade biscotti, and soothing teas.

At IDEO London, we held an office-wide Valentine’s Day celebration with activities and treats under the theme of Random Acts of Love. We set up areas to collect clothes and food for those more in need, and a station to create a heart chain of messages to people across IDEO locations, hoping they’d continue the chain. Prior to the event, we asked everyone to send us one song they’d take to a desert island and why. Over a selection of strawberry daiquiris and fresh cupcakes, we filmed people talking about their chosen song. We had tears and goosebumps. Interestingly, most people chose songs to remind them of someone they love dearly. Three others chose songs that have helped them get through life.

This is a fortune my boyfriend and I got on one of our first trips together, before we were "officially" dating. Something told me to hold onto it. Later, he had this greeting card printed for me for Valentine's Day. He actually had to print a minimum of 100 so somewhere we have a hefty stack of personalized greeting cards of ourselves. Over 3 years later, I still have the fortune.

I used to work for a company that was pretty hardcore about celebrating Valentine's Day. We would exchange gifts, play games, have a big party, etc. One year I made this clock for my good friend and former colleague Irene Pau. The design is inspired by an inside joke that's probably not worth going into here. But the main goal was really just to make something weird that would creep her out, and also help her get to meetings on time. Mission accomplished?
—Griffin Thomson, IDEO Palo Alto

I love giving people Spanish Sweethearts for Valentine’s Day. They’re unique (read: hard-to-find) and everyone learns some Spanish from my gift!
—Katie Clark, IDEO San Francisco

Kiley was our New York front desk concierge for a couple of years, and she decided to leave last year to head to Arkansas and pursue writing and graduate school. She always put a lot of work into making the office feel special, so we decided to throw her a big going away party to show our appreciation. The base of the K was cut from scrap foam core on the laser cutter. The colored fringe was created from discarded Post-it pad slivers that were collecting in the hallway, which were stuck onto the K then cut vertically. Try your own letter piñata for Valentine's Day!

When choosing a gift for your Valentine, why settle for a store-bought card? Drop that box of chocolates and steal these IDEO designers' crafty, hacky, wacky ideas for celebrating the holiday of love. Or better yet, try dating a designer! There’s bound to be a good gift in it for you.

I help organizations cut through complexity by shaping how they show up, through brand strategy, identity, and storytelling.

Working at the intersection of brand and business, I bring an editorial eye and a bias toward making—turning ideas into tangible experiences that people can understand, trust, and believe in.

My work spans government, healthcare, financial services, media, and consumer goods, from launching Gen Z-focused ventures to building innovation labs and reimagining legacy brands. I relish moments of ambiguity and enjoy translating across teams, perspectives, and priorities to move ideas forward.

I started my career in editorial and digital design, shaping cross-platform experiences and identity systems in publishing and agency environments. That foundation still shapes how I work today: I’m detail-oriented, collaborative, and overreliant on the Oxford comma. I hold a BFA in Visual Communication from the School of the Art Institute of Chicago.

For 25 years, I've asked the same question: Who does this design exclude—and what are we going to do about it?

My work spans human-centered strategy, inclusive design, and qualitative research, with clients ranging from Microsoft, Google, and Verizon to the National Science Foundation, and San Francisco Unified School District.

Before IDEO, I taught elementary school in East Palo Alto and spent a decade doing design work with social service organizations—where I learned firsthand what it costs people when systems are built without them in mind.

I am currently writing User Error, a nonfiction book about digital access and the design decisions behind it. I live in Oakland, California.

‍

My expertise spans brand, communication, and product design across tech, education, the arts, and social impact.

I believe great work demands both high-level vision and obsessive attention to detail, and only happens through collaboration.

I bring an inclusive, hands-on approach and a deep understanding of business, which enables me to consistently deliver excellence while always asking why.

Before joining IDEO, I worked at the brand firms Pentagram and VSA Partners. I began my career as a designer, leading teams at the School of the Art Institute of Chicago and the Milwaukee Art Museum. I hold an MFA in graphic design from Maryland Institute College of Art and a BFA in communication design from the Milwaukee Institute of Art & Design, and have taught at some of the best design schools in the US.

I am responsible for IDEO’s long-term success in China and working with clients to use design as a tool to enable growth. Specifically, I have helped Chinese companies design holistic brand solutions through the development of their products, communication, services, and innovation teams, and I have helped multinationals expand their presence and influence in China.

I advise global leaders on developing China-led innovation and capabilities.

In over 15 years in IDEO Shanghai, I have worked on projects that use design to elevate the quality of the experience of healthcare products and services, streamline processes that increase productivity, create spaces and programs that promote and enable inclusive communities, and build next generation mobility solutions that are planet-positive.

Before joining IDEO, I worked at Philips Electronics and the Electrolux Group in Italy, the Netherlands, and Singapore on a number of breakthrough commercial products. I am a member of the Young President Organization in Shanghai.

Most AI products today are built for work—a space with clear problems and established systems. One founder noticed a gap: personal life is messier, harder to systematize, and mostly left behind by the AI boom. So she built Cue, a personal AI that lives inside iMessage and group chats, to go where the other tools haven't.

‍

In this episode, Becca Carroll, IDEO's Chief Strategy Officer, talks with Sida Li, co-founder and CEO of Shared Context Lab, about staying anchored to a human need while the technology around her keeps changing shape, why she treats her business model with the same rigor she'd bring to a product, and what it feels like to build a company at this particular, disorienting moment in AI.

‍

The conversation also gets into how Sida makes design decisions: the language Cue uses to describe itself, the tradeoffs behind building inside iMessage instead of a new app, and a real story about a business idea that didn’t pan out.

‍

This is the second in a two-part series profiling founders from IDEO's Startups-in-Residence program. The first conversation is with Johannes Seemann, founder of Sooner, on designing GenAI for the emotional side of money.

Most personal financial tools are built to run the numbers and optimize towards a budget. While that works for some, most people experience money as a lived relationship that does not neatly fit into a spreadsheet. Johannes Seemann and Becca Carroll discuss why money is emotional before it is mathematical, and what a human-centered approach to building a generative AI financial product looks like in practice.

Mina Seetharaman talks with Scott Shigeoka, author of Seek and Head of Curiosity Cultivation at the Eames Institute, about what distinguishes genuinely curious leadership from performative curiosity, how power dynamics shape curiosity, and why practicing curiosity can restore energy rather than drain it.

Mina Seetharaman talks with David Epstein, author of Inside the Box and Range, about why total freedom often produces average work, how leaders can design useful limits on purpose, and what organizations such as General Magic and Pixar reveal about the relationship between boundaries and creativity.
